ABSTRACT

Abstract Introduction: Among the main causes of death in Colombia, Latin America, and the general population are pathologies of cardiovascular origin, which have an important relationship with dyslipidemias. Objective: The objective of the study was to establish the prevalence of the use of lipid-lowering drugs in a Colombian population during 2016. Material and methods: A cross-sectional study was conducted using a population database of the Colombian Health System between January and June 2016. Site: outpatients of Colombia. Participants. Researchers considered all patients who had received this class of drug to establish the prevalence of the use of lipid-lowering drugs. Main measurements. Prevalence of use of lipid-lowering drugs. Results: From a population of 4,328,688 patients, a total of 282,002 were prescribed a lipid-lowering drug; the mean age was 64.2 ± 13.3 years and women comprised 50.4% of the users. The estimated prevalence of lipid-lowering drug use was 6.5%. Statins (86.3%) were the most commonly used lipid-lowering drugs (atorvastatin: 81.0%, lovastatina: 14.4%) followed by fibrates (13.1%) and ezetimibe (0.6%). Conclusions: A low proportion of people are being treated with lipid-lowering drugs, according to the estimated prevalence of dyslipidemia.

ABSTRACT

The accessory ß1 subunits, regulating the pharmacological and biophysical properties of BK channels, always undergo post-translational modifications, especially glycosylation. To date, it remains elusive whether the glycosylation contributes to the regulation of BK channels by ß1 subunits. Methods: Herein, we combined the electrophysiological approach with molecular mutations and biochemical manipulation to investigate the function roles of N-glycosylation in ß1 subunits. Results: The results show that deglycosylation of ß1 subunits through double-site mutations (ß1 N80A/N142A or ß1 N80Q/N142Q) could significantly increase the inhibitory potency of iberiotoxin, a specific BK channel blocker. The deglycosylated channels also have a different sensitivity to martentoxin, another BK channel modulator with some remarkable effects as reported before. On the contrary to enhancing effects of martentoxin on glycosylated BK channels under the presence of cytoplasmic Ca2+, deglycosylated channels were not affected by the toxin. However, the deglycosylated channels were surprisingly inhibited by martentoxin under the absence of cytoplasmic Ca2+, while the glycosylated channels were not inhibited under this same condition. In addition, wild type BK (α+ß1) channels treated with PNGase F also showed the same trend of pharmacological results to the mutants. Similar to this modulation of glycosylation on BK channel pharmacology, the deglycosylated forms of the channels were activated at a faster speed than the glycosylated ones. However, the V1/2 and slope were not changed by the glycosylation. Conclusion: The present study reveals that glycosylation is an indispensable determinant of the modulation of ß1-subunit on BK channel pharmacology and its activation. The loss of glycosylation of ß1 subunits could lead to the dysfunction of BK channel, resulting in a pathological state.(AU)

ABSTRACT

Realizando a ponte entre a farmacologia homeopática (princípio da similitude) e a farmacologia moderna, encontramos uma infinidade de relatos, tanto em compêndios farmacológicos como em experimentos e ensaios clínicos publicados em periódicos científicos, que descrevem uma reação do organismo oposta e secundária a uma ação primária da droga, confirmando a teoria hahnemanniana. Essa ação secundária do organismo, no sentido de manter a homeostase orgânica, é denominada de efeito rebote ou reação paradoxal segundo a racionalidade científica moderna, sendo usada pela homeopatia como resposta terapêutica. (AU)


Building a bridge between homeopathic pharmacology (principle of similitude) and modern pharmacology, one can find countless reports in pharmacological compendia and clinical and experimental trials published in the scientific media describing the secondary reaction of the organism opposed to the primary action of the drug, which confirm Hahnemann's theory. Such secondary action of the organism to preserve organic homeostasis is known in modern science as rebound effect or paradoxical reaction, being used by homeopathy as a therapeutic response.(AU)

ABSTRACT

Seguindo a mesma dinâmica da homeopatia clássica, essa obra sistematiza uma proposta para empregar os fármacos modernos segundo o princípio da similitude terapêutica, estimulando o efeito rebote (reação vital) curativo do organismo através da administração de substâncias (em doses dinamizadas) que despertaram sintomas semelhantes no estado de saúde humano. Vale ressaltar que os efeitos patogenéticos (ações primárias) dos medicamentos homeopáticos clássicos correspondem aos efeitos terapêuticos, adversos e colaterais dos fármacos modernos, os quais devem apresentar uma totalidade sintomática semelhante ao do paciente para estimular a reação vital curativa (efeito rebote curativo), de acordo ao princípio da similitude terapêutica. Para viabilizar essa proposta, foi necessário elaborar uma Matéria Médica Homeopática dos Fármacos Modernos, agrupando os efeitos terapêuticos, adversos e colaterais das drogas conforme a disposição anátomo-funcional dos capítulos das matérias médicas homeopáticas tradicionais, valorizando a frequência de manifestação dos sintomas observadas nas fases de estudo da droga. Como segundo passo, para facilitar a seleção do medicamento individualizado (semelhança com a totalidade de sintomas do paciente) e a aplicação clínica da proposta, foi elaborado um Repertório Homeopático dos Fármacos Modernos, dispondo os sintomas e seus respectivos medicamentos de forma análoga aos repertórios homeopáticos tradicionais, descrito em outra obra desta coleção. (AU)


Following the pattern of traditional homeopathy, this work proposes to employ modern drugs according to the principle of therapeutic similitude, stimulating the healing rebound effect (vital reaction) of the organism through the administration of substances (in infinitesimal doses) that caused similar symptoms in healthy human. Is worth emphasizing that the pathogenetic effects (primary actions) of classical homeopathic medicines correspond to the therapeutic, adverse and side effects of conventional drugs, which should be similar to totality of the symptoms of the patient to stimulate the curative vital reaction (curative rebound effect) according to the principle of therapeutic similitude. To make this proposal operative, a Homeopathic Materia Medica of Modern Drugs was elaborated, where the therapeutic, adverse and side effects of drugs were grouped following the structure of the traditional homeopathic materia medica, while giving particular value to the frequency of the symptoms observed during the phases of study of the drugs. In order to facilitate the selection of the individualized remedy (i.e., similar to the totality of symptoms of the patient), and thus the clinical application of the present proposal, at a later stage it was also elaborated a Homeopathic Repertory of Modern Drugs, where symptoms and remedies are arranged as in the traditional homeopathic repertories, described in another work of this collection.

ABSTRACT

Abstract Introduction: improper use of medication is becoming more frequent and can cause physical or physiological damage. Objective: to determine the frequency of potentially inappropriate prescriptions of cardiovascular drugs according to Beers' criteria in a population of colombian patients. Method: cross-sectional study conducted during november 2016 using a population database of 326,192 adults over 65 years of age who were eligible to receive drugs included in the cardiovascular system category according to the Beers' criteria. The frequency of potentially inappropriate prescriptions was determined and investigated in relation to sociodemographic variables. Results: the mean subject age was 74.6±7.6 years (range:65-100 years). It was found that 11.3% (n=36894) of the elderly presented at least one potentially inappropriate prescription for cardiovascular conditions. The most frequent finding was the use of aspirin in patients older than 80 years of age followed by the use of prazosin for hypertension in patients over 65 years of age or in patients who consulted emergency services for syncope. The other criteria were present in less than 1% of patients, and in 16 out of 33 treatment drugs, no patients exposed to potentially inappropriate prescriptions were found. Within the criteria based on drug-drug interactions, the most frequent were loop diuretics along with prazosin (6.4%). Conclusions: the prevalence of potentially inappropriate prescriptions in an elderly population of patients in Colombia is lower than that reported worldwide. In addition, there is a need to re-evaluate the Beers' criteria in this population and adjust the guidelines according to results of pharmacovigilance of active pharmaceutical substances available in Colombia.


Resumen Introducción: el uso incorrecto de medicamentos es cada vez más frecuente y puede causar daños físicos o fisiológicos. Objetivo: determinar la frecuencia de las prescripciones de medicamentos de uso cardiovascular potencialmente inapropiadas según criterios de Beers en una población de pacientes colombianos. Métodos: estudio de corte transversal, a partir de una base de datos de una población de 326.192 adultos mayores de 65 años, durante el mes de noviembre de 2016, susceptibles de recibir medicamentos incluidos en los criterios de Beers en la categoría de sistema cardiovascular, determinando la frecuencia de prescripciones potencialmente inapropiadas, así como la identificación de variables sociodemográficas. Resultados: la edad promedio fue de 74,6±7,6 años (rango 65-100 años). Se halló que el 11,3% (n=36894) de los ancianos tuvo al menos una prescripción potencialmente inapropiada para condiciones cardiovasculares. El criterio más frecuente fue el uso de aspirina en mayores de 80 años, seguido del empleo de prazosín para la hipertensión arterial en mayores de 65 años, o en pacientes que consultaron por síncope a los servicios de urgencias. Los demás criterios se presentaban en menos del 1% de pacientes y en 16 de 33 fármacos de cuidado no se halló ningún paciente expuesto. Entre los criterios basados en interacciones fármaco-fármaco, el más frecuente fue diuréticos de asa junto con prazosín (6,4%). Conclusiones: la prevalencia de prescripciones potencialmente inapropiadas en una población de ancianos colombianos es menor a la reportada en el mundo. Además, se plantea la necesidad de reevaluar los criterios de Beers en dicha población y ajustarlos de acuerdo con los informes de farmacovigilancia y principios activos disponibles en Colombia.

ABSTRACT

The interventional cardiology is growing and evolving. Many complex procedures are now performed outside the operating room to manage cardiovascular pathologies which had been traditionally treated with cardiac surgery. Appropriate sedation strategy is crucial for improved patient comfort and successful procedure while ensuring safety. Sedation for cardiovascular intervention is frequently challenging, especially in critically-ill, high-risk patients. This review addresses pre-procedure evaluation and preparation of patients, proper monitoring, commonly used sedatives and analgesics, and considerations for specific procedures. Appropriate depth of sedation and analgesia should be balanced with patient, procedural and institutional factors. Understanding of the pharmacology of sedatives/analgesics, vigilant monitoring, ability and proper preparation for management of potential complications may improve outcomes in patients undergoing sedation for cardiovascular procedures.

ABSTRACT

Emerging and re-emerging RNA viruses occasionally cause epidemics and pandemics worldwide, such as the on-going outbreak of the novel coronavirus SARS-CoV-2. Herein, we identified two potent inhibitors of human DHODH, S312 and S416, with favorable drug-likeness and pharmacokinetic profiles, which all showed broad-spectrum antiviral effects against various RNA viruses, including influenza A virus, Zika virus, Ebola virus, and particularly against SARS-CoV-2. Notably, S416 is reported to be the most potent inhibitor so far with an EC of 17 nmol/L and an SI value of 10,505.88 in infected cells. Our results are the first to validate that DHODH is an attractive host target through high antiviral efficacy in vivo and low virus replication in DHODH knock-out cells. This work demonstrates that both S312/S416 and old drugs (Leflunomide/Teriflunomide) with dual actions of antiviral and immuno-regulation may have clinical potentials to cure SARS-CoV-2 or other RNA viruses circulating worldwide, no matter such viruses are mutated or not.

ABSTRACT

OBJECTIVE@#To compare intranasal midazolam and intramuscular phenobarbital sodium for their sedative effect in neonates undergoing magnetic resonance imaging (MRI).@*METHODS@#A total of 70 neonates who underwent cranial MRI from September 2017 to March 2019 were randomized into an observation group and a control group, with 35 cases in each group. The observation group received intranasal drops of midazolam (0.3 mg/kg), and the control group received intramuscular injection of phenobarbital sodium (10 mg/kg). The sedation status of the neonates was evaluated using the Ramsay Sedation Scale. Meanwhile, the two groups were compared for the success rate of MRI procedure and incidence of adverse reactions.@*RESULTS@#In the observation group, the sedation score was the highest at 20 minutes post administration, then was gradually decreasing, and decreased to the lowest level at 70 minutes post administration. In the control group, the sedation score was the lowest at 10 minutes post administration, then was gradually increasing, and increased to the highest level at 40 minutes and 50 minutes post administration, followed by a gradual decrease. Comparison of the sedation score at each time period suggested that the sedation score was significantly higher in the observation group than in the control group within 40 minutes post administration (P0.05). The success rate of MRI procedure was significantly higher in the observation group than in the control group (89% vs 69%, P0.05).@*CONCLUSIONS@#Intranasal midazolam is superior to intramuscular phenobarbital sodium in the sedative effect in neonates undergoing MRI, with the benefits of being fast, convenient, safe, and effective.

This work demonstrates that both S312/S416 and old drugs (Leflunomide/Teriflunomide) with dual actions of antiviral and immuno-regulation may have clinical potentials to cure SARS-CoV-2 or other RNA viruses circulating worldwide, no matter such viruses are mutated or not.

ABSTRACT

OBJECTIVE@#To establish a clinically applicable model of rapid identification of adverse drug reaction program (RiADP) for risk management and decision-making of clinical drug use.@*METHODS@#Based on the theory of disproportion analysis, frequency method and Bayes method, a clinically applicable RiADP model in R language background was established, and the parameters of the model were interpreted by MedDRA coding. Based on the actual monitoring data of FDA, the model was validated by the assessing hepatotoxicity of lopinavir/ritonavir (LPV/r).@*RESULTS@#The established RiADP model included four parameters: standard value of adverse drug reaction signal information, empirical Bayesian geometric mean value, ratio of reporting ratio and number of adverse drug reaction cases. Through the application of R language parameter package "phViD", the model parameters could be output quickly. After being encoded by MedDRA, it was converted into clinical terms to form a clinical interpretation report of adverse drug reactions. In addition, the evaluation results of LPV/r hepatotoxicity by the model were matched with the results reported in latest literature, which also proved the reliability of the model results.@*CONCLUSIONS@#In this study, a rapid identification method of adverse reactions based on post marketing drug monitoring data was established in R language environment, which is capable of sending rapid warning of adverse reactions of target drugs in public health emergencies, and providing intuitive evidence for risk management and decision-making of clinical drugs.

ABSTRACT

Cullin-RING E3 ligases (CRLs) are the major components of ubiquitin-proteasome system, responsible for ubiquitylation and subsequent degradation of thousands of cellular proteins. CRLs play vital roles in the regulation of multiple cellular processes, including cell cycle, cell apoptosis, DNA replication, signalling transduction among the others, and are frequently dysregulated in many human cancers. The discovery of specific neddylation inhibitors, represented by MLN4924, has validated CRLs as promising targets for anti-cancer therapies with a growing market. Recent studies have focused on the discovery of the CRLs inhibitors by a variety of approaches, including high through-put screen, virtual screen or structure-based drug design. The field is, however, still facing the major challenging, since CRLs are a large multi-unit protein family without typical active pockets to facilitate the drug design, and enzymatic activity is mainly dependent on undruggable protein-protein interactions and dynamic conformation changes. Up to now, most reported CRLs inhibitors are aiming at targeting the F-box family proteins (e.g., SKP2, β-TrCP and FBXW7), the substrate recognition subunit of SCF E3 ligases. Other studies reported few small molecule inhibitors targeting the UBE2M-DCN1 interaction, which specifically inhibits CRL3/CRL1 by blocking the cullin neddylation. On the other hand, several CRL activators have been reported, such as plant auxin and immunomodulatory imide drugs, thalidomide. Finally, proteolysis-targeting chimeras (PROTACs) has emerged as a new technology in the field of drug discovery, specifically targeting the undruggable protein-protein interaction. The technique connects the small molecule that selectively binds to a target protein to a CRL E3 via a chemical linker to trigger the degradation of target protein. The PROTAC has become a hotspot in the field of E3-ligase-based anti-cancer drug discovery.

ABSTRACT

OBJECTIVE@#To explore the effects of taurolithocholic acid (tLCA) and chenodeoxycholic acid (CDCA) on the expression of aorexigenic neuropeptide in mouse hypothalamus GT1-7 cells.@*METHODS@#Mouse hypothalamic GT1-7 cells were treated with culture medium containing 10% FBS (control group, =3) or with 10 nmol/L, 100 nmol/L, 1 μmol/L and 10 μmol/L tLCA (tLCA group, =3) or CDCA (CDCA group, =3) for 12, 24 or 48 h. Real-time PCR was performed to determine the expression levels of proopiomelanocortin (POMC) mRNA in the cells, and the production levels of α-melanocyte-stimulating hormone (α-MSH) were assessed using an ELISA kit. Signal transduction and activator of transcription 3 phosphorylation (p-STAT3), threonine kinase phosphorylation (p-AKT), suppressor of cytokine signaling 3 (SOCS3), G protein-coupled bile acid receptor-1 (TGR5) and farnesoid X receptor (FXR) protein were detected by Western blotting.@*RESULTS@#Western blotting results showed that mouse hypothalamic GT1-7 cells expressed two bile acid receptors, TGR5 and FXR, whose expressions were regulated by bile acids. Real-time PCR showed that the expression of POMC mRNA was significantly increased in the cells after treatment with 10 μmol/L tLCA or CDCA for 24 h. POMC-derived anorexigenic peptide α-MSH increased significantly in GT1-7 cells after treatment with 10 μmol/L tLCA or CDCA for 24 h. Treatment of the cells with tLCA or CDCA significantly increased the expressions of intracellular signaling proteins including p-STAT3, p-AKT and SOCS3.@*CONCLUSIONS@#Mouse hypothalamic GT1-7 cells express bile acid receptors TGR5 and FXR. Bile acids tLCA or CDCA can promote the expression of POMC mRNA and increase the production of the anorexigenic peptide α-MSH. The intracellular signaling proteins p-AKT, p-STAT3 and SOCS3 are likely involved in bile acid-induced anorexigenic peptide production.
